Aw, so sorry, but direct quote characters are not allowed. You can keep the three sword style, but if you would: Change the name, the picture of the character and don't make anymore similarities between you and Zoro.

No... you must add your own original techniques. You have already adopted the fighting style of a character from one piece while Zoro has pretty pwnage moves. It is up to you to prove your creativity by making up your own. It's more than just changing the names.

Naturally... when you make a character of your own design, and put the work in to make them original and of your own imagination you become attached to them in more ways than one. Anyone can adopt the strongest characters from any anime and bring them here if that was allowed.
